METAL-WORKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 721,841, dated March 3, 1903.

Application filed January 20, 1902. Serial No. 90,562. (No modeh) To all whom it may concern.

Be it known that I, WILLAM T. SEARS, a citizen of the United States, residing at Onslow, in the county of Jones a'ndState of Iowa, have invented a new and useful Metal-Working Machine, of which the following is a specification.

The invention relates to a combined punching, shearing, and plow-welding machine.

The object of the present invention is to provide a combined machine of simple and comparatively inexpensive construction adapted for punching, shearing, and plow-welding and provided with a saw-glimmer and capable of simultaneously operating the several parts, whereby any one of the operations of the machine may be performed without interchanging, removing, or rearranging the parts.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 designates a lower stationary jaw, formed integral with a fiat base 2 and cooperating with an upper movable jaw 3, pivoted at its rear end or portion to the stationary jaw by a transverse bolt 4 and arranged at one side of the stationary jaw approximately over the center of the base, and the said bolt4= is supported by a vertical brace 5, arranged at the outer side of the movable jaw. The brace 5, which is located at one side of the base-plate, near the rear end thereof, has a perforated car at its upper end to receive the bolt 4, and it is provided at its lower end with an outwardly-extending horizontal flange 6, which is bolted or otherwise secured to the baseplate. The base is provided at its ends with dovetailed ways 7, arranged at its lower face and receiving tapering or dovetailed blocks '8, arranged at the upper ends of and forming heads for legs 9 and adapted to be secured in the dovetailed ways in any suitable manner. The base is also provided at its ends with approximately L-shaped brackets or plates 10, bolted or otherwise secured at their upper ends to the base and provided at their lower portions or arms with perforations for the re ception of hooks 11. The stationary jaw and the base constitute the body portion or frame of the machine, which is provided at its front with an upright curved rack 12, formed integral with the said frame and provided at opposite sides with flanges 13,which are engaged by flanges 14 of approximately L-shaped links 15, which connect an operating-lever 16 with the front end of the movable jaw. The teeth of the rack are arranged at the front edge of the frame, and the L-shaped links, which are located at oppositesides of the rack-bar, have upwardly extending long arms and rearwardly-extending short arms, the flanges 14 being arranged at the inner faces of the short arms at the ends thereof. The short arms of the links are detachably interlocked with the front of the frame, and the flanges 13 form ways for the said links. Between the links is arranged a gear wheel or pinion 17, which meshes with the rack-bar and which is adjustably interlockedwith the operating-lever 16 by means of a removable key 18, which passes through the lever. When the key 18 is removed and the L-shaped links are disengaged from the upper jaw 3, the pinion is free to rotate, and the said L-shaped links are free to slide off the front end of the frame out of engagement with the side flanges 13 thereof. The key by limiting the movement of the pinion also prevents the links from sliding too far on the frame and becoming disengaged from the side flanges 13. By this construction the parts may be readily assembled and adjusted to secure a proper operation of the machine. The lever is composed of upper and lower sections, the upper or outer section consisting of a suitable bar or member and the inner or lower section being provided with a socket 19 for the reception of the bar or member, which is removable and which is also provided between its ends with a bend to arrange the outer portion at an angle to the inner portion. The inner or lower section of the operating-leveris provided with a bifurcated end 20, which is enlarged to receive the links and the gear and which is perforated for the reception of the said key 18 and for a pivot 21, upon which the pinion is mounted and which preferably consists of a bolt. When the key 18 is withdrawn from the opening or perforation of the bifurcated end of the operating-lever, the latter is adapted to swing independently of the pinion and may be arranged in different positions with relation to the pinion, and it is fixed to the same in its adjusted position by means of the key. \Vhen the operating-lever is oscillated, the pinion is partially rotated and the links are carried upward and downward on the rack-bar, and their upper ends are perforated for the reception of a pivot 22 for connecting the links to the movable jaw. The oscillation of the operating-lever moves the upper pivoted jaw 3 to and from the stationary jaw and operates the punching, shearing, and plow-welding devices hereinafter described.

The stationary and movable jaws are provided at their adjacent edges with suitable blades or cutters 23 and 24, and in order to hold the material in position a loop or frame 25 is hinged to the main frame of the machine at the outer face of the stationary jaw and is provided with a substantially oblong opening and is adapted to extend above the upper face of the stationary jaw to receive the material to be cut. The loop or frame is provided with perforated ears 26, arranged in pairs at opposite sides of ears 27 of the frame of the machine and hinged to the same by a pintle 28. The loop or frame 25 is adapted to hang down out of the Way when it is not in use, as illustrated in Fig. 1 of the drawings.

The stationary jaw, which is located above the base, is connected with the same by the enlarged portion of the front of the main frame and by a depending portion or arm 29, and it has an enlargement 30 at its inner face. The enlargement 30 forms the inner section of a guide or casing, which is provided with an outer section 31, having recesses 32 at opposite sides to receive projecting ears 33, which are perforated for the reception of a pin or key 34.

The sections 30 and 31 are arranged vertically and are provided at their inner opposite faces with grooves forming a vertical bore or opening for a punch 35. The pin or key 34 is arranged at the outer face of the removable section 31,and the latter is firmly interlocked with the projecting ears or flanges 33 by the upper and lower shoulders formed by the recesses 32. The plunger is provided at its lower end with a suitable socket, and it has aclampingscrew 36 for securing a bit or tool 37 in the socket, and its upper end is connected with the movable jaw 3 by means of a connectingplate 38, pivoted to the movable jaw by a bolt or other suitable fastening device 40, and provided at its lower end with an inwardly-extending arm, terminating in a pivot 41. The pivot 41 of the connecting-plate extends beneath the movable jaw and is arranged in a perforation or opening 42 of the upper end of the punch. By this construction the punch is detachablyinterlocked with the connecting-plate and is vertically reciprocated when the upper jaw is oscillated. The punch cooperates with an adjustable die 43, provided with openings of various sizes and consisting of a block or body 44 and a plate 45, which may be secured to the body or block 44 in any suitable manner. The block or body is provided with a slot 46, having an enlarged portion or recess 47 for the reception of the head of a bolt 48, which passes through the slot 46 and through a slot 49 of the base of the machine. The bolt is approximately T-shaped, and its lower end is threaded for the reception of a nut 50, which is provided with an arm or handle by means of which it is rotated. The die is oblong, and the plate is suitably mounted on the block. The die is adapted to be adjusted longitudinally. of the main frame of the machine, and it is capable of rotation to bring any of its openings directly beneath the punch.

The rear end of the machine has mounted upon it a saw-gummer which is provided with a spring supported punch or plunger 51, mounted in a suitable guide or casing 52, having a vertical tubular portion and provided at its bottom with a base, which is suitably secured to the base of the main frame. The plunger is provided at its lower end with a suitable saw-engaging portion and is adapted to operate on the saw-blade in the usual manner, and it is normally supported in an elevated position by a coiled spring 53, disposed on the upper portion of the plunger and interposed between the top of the casing or guide and a pin or key 54; but any other suitable stop or shoulder may be provided for engaging the upper end of the spring. The

upper end of the plunger is located beneath an arm or lug 55, preferably consisting of an enlargement of the rear end of the movable jaw and having a flat lower face arranged to engage and depress the plunger when the frontportion of the movable is r'aised. The casing or guide of the saw-gummer is provided with a suitable anvil "Qr seat for a saw-blade, and it may be constructedin any suitable'manner, andits lower portion is provided with slots or openings to enable a sawblade to be passed beneath'the plunger.

Mounted upon the front portioii 'of the base of the machine, at oneisidethereof,'is a stationary plow-welding jaw 56, having its inner port-ion resting uponlthe base of the machine and provided adjacent to thesame with a downwardly-extending fl ange o'l', which fits against the edge of the base; The fixed weld-' ing-jaw is provided at the front ith an ear 57, and it has a way 58 for the reception of a clamp 59, which is capable of i iiward and outward movement and which is-provided with an engaging portion or flange 60, cooperating with an upwardly-extending engaging portion or flange 61 of the lower stationary weldingjaw and adapted to hold the parts to be welded. The way 58 c onsists of a recess, the lower welding-jaw being provided at opposite sides with longitudinal flanges and the clamping-plate being fitted snugly between the flanges and retained in place by a plate 62, suitably secured to the lower welding-jaw and arranged upon the side flanges thereof. The clamping-jaw is provided with a recess 63, which receives the head of a cam-lever 64, and the latter is adapted to be oscillated to move the clamp inward and outward and is capable of holding the same firmly in engagement with the parts to be welded, and it is provided with a suitable pivot mounted in perforations of the lower welding-jaw and the plate 62 thereof. The perforated car 57 receives a pivot-bolt 65, which connects the jaw with the frame of the machine and which permits the said lower welding-jaw to be swung upward out of the way when it is desired to obtain greater space or room at the base of the machine, which is adapted to serve as a bench. The movable jaw has mounted upon it an upper weldingjaw 66, connected to the movable jaw 3 by a bolt 67 or other suitable pivot and adapted to cooperate with the lower welding-jaw for welding together the plowshare and the landside of a plow. The upper welding-jaw can also be swung upward out of the way when it is desired to obtain a large amount of space at the base of the frame of the machine; but the plow-Welding device, the punch, the sawgummer, and the cutters may be simultaneously operated, and any one of the operations of the machine may be performed without removing, changing, or rearranging the parts of the machine.

It will be seen that the machine is simple and comparatively inexpensive in construction, that it is easily operated by simply oscillating the lever, and that the various devices are simultaneously operated, so that any one of them may be used. It will also be apparent that ready access is afforded to the parts of the machine and that the parts maythe minor details of construction within the scope of the appended claims may be resorted to without departing from the spirit or sacrificing any of the advantages of this inven tion.
